Gift box container

ABSTRACT

A package is provided comprising a tray having a main panel and opposed side walls and opposed end walls which are each hinged to the main panel. The package further comprises a stiffening sheet comprising a base panel having opposed side panels and opposed end panels hinged thereto, wherein at least one of the opposed end panels of the stiffening sheet includes a securing tab. The securing tab is defined at least in part by a weakened line of severance and is secured to the tray. The securing tab is severed from the stiffening sheet when the tray is erected from a flat collapsed form into a set up condition.

FIELD OF INVENTION

The present invention relates generally to gift box containers for packaging an article or articles, and more particularly, but not exclusively, to a method of construction and assembly of double walled gift boxes.

BACKGROUND OF INVENTION

Double walled gift boxes are known. Covers and bases are usually formed from relatively flexible paperboard blanks having decorative outer surfaces and flat, clean inner surfaces. Side and end walls are folded inward upon themselves to form double walls adhered together by adhesives. Inner portions of the walls are connected by creased gussets which are folded and tucked into junctions of the side and end walls. Glue strips connect inner and outer portions of the walls. Folded gussets are held in place by the glue strips.

Reinforcement of the double walled gift boxes with heavier sheets is sometimes useful. When larger, heavier sheets are added to boxes an alignment of the sheets to which the adhesive has been applied may become a problem; U.S. Patent Application Publication No. 2005/0092821 A1 discloses such a gift box. There is still a need for improved boxes and methods of construction which reduce defects while simplifying equipment and processes. It is known that when heavier sheets are secured with adhesive or other securing means, such adhesive or other securing means may break away during the construction or assembly process. It is therefore desirable to reduce or at least mitigate the problems of the prior art.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE PRESENT INVENTION

A preferred embodiment of the present invention is shown in FIGS. 1 to 12. FIG. 1 illustrates a blank 20 for forming a tray 1 as illustrated in FIG. 13, of a double walled gift box (as shown in FIG. 13). The blank 20 comprises a main panel 12 which may form the base of a base box, or the top panel of a cover. Outer side walls 14 a, 14 b are hingedly connected to opposed sides of the main panel 12 along fold lines 32 a, 32 b respectively.

Inner side walls 16 a, 16 b, are hingedly connected outer side walls 14, 14 b, respectively along respective fold lines 34 a, 34 b. Inner side walls 16 a, 16 b, each comprise a pair of tabs 26 hinged to opposed ends of the inner side walls 16 a, 16 b, along fold lines 27. The tabs 26 are disposed adjacent to the fold line 34 a, 34 b, separating the inner and outer side walls, 14 a, 14 b and 16 a, 16 b.

Outer end walls 18 a, 18 b are hinged to opposed ends of the main panel 12 along fold lines 36 a, 36 b respectively. Inner end walls 20 a, 20 b, are hinged to respective ones of said outer end walls 18 a, 18 b along fold lines 38 a, 38 b respectively. Inner end walls 20 a, 20 b, each comprise a tab 24 disposed centrally on the free edge 37 opposed the hinged edge defined by fold line 38 a, 38 b. The side edges of the inner end wall 20 a, 20 b comprise a recess portion 21 disposed adjacent to the fold line 38 a, 38 b.

The recess 21 is substantially similar in dimension to tab 26. The remaining portion of the side edge forms an engaging edge 22, such that in an assembled form the portion 22, engages beneath tab 26, between the outer side wall 18 a, 18 b, and the end edge 25, of the inner side wall 16 a, 16 b.

The end edge 25 of the inner side wall is offset from an end edge defined by fold line 31 of the outer side wall 14 a, 14 b; such that at least a portion of the inner side wall 16 a, 16 b is shorter in length than the outer side wall 14 a, 14 b. This arrangement provides a space between the end edge of the inner side wall 25, and the inside surface of the end walls 18 a, 18 b. This space is sufficient to accommodate the engaging edge 22 of the sides of inner end walls 20 a, 20 b such that the edge of the inner side wall 25 and engaging edge 22 form a complementary locking mechanism for securing the inner end walls 20 a, 20 b without the need for adhesive.

A first gusset panel 28 hinged to each side edge of outer end wall 18 a, 18 b along a fold line 38. A second gusset panel 30 is hinged to each of said first gusset panels 28 along a fold line 33 and to each end edge of the outer side panels 14 a, 14 b.

A further complementary locking mechanism is formed in part by tab 24 and in part by aperture 46 struck from stiffener sheet 10, as shown in FIG. 2.

Stiffener sheet 10, shown in FIG. 2, comprises a main panel 40 and a pair of opposed side panels 42 a, 42 b hinged to opposed side edges along fold lines 48 a, 48 b respectively. Trapezoidal opposed end panels 44 a, 44 b, are hinged end edges of the main panel 40 along fold lines 50 a, 50 b.

A tab 60 is formed in trapezoidal opposed end panels 44 a, 44 b. Tab 60 is defined in part by aperture 46 and in part by a weakened line 61. Aperture 46, is struck in part from trapezoidal opposed end panel 44 a, 44 b and in part from main panel 40.

In the illustrative embodiment, the opposed end panels are trapezoidal in shape, although it will be appreciated by those skilled in the art that alternative shapes may be used.

Furthermore, whereas in the illustrative embodiment the tab 60 is struck from the trapezoidal opposed end panel 44 a, 44 b; it will be appreciated that alternative configurations could be employed without departing from the scope of the invention.

In the exemplary embodiment stiffening sheet 10 is dimensioned such that main panel 40 is smaller that main panel 12 of the tray forming blank 20. This allows tray forming blank 20 to be readily folded about the stiffening sheet 10 without the stiffening sheet initiating the folding process and provides a mechanism for securing the stiffening sheet to the tray forming blank whist further processing is carried out.

Turning now to the construction of the tray of the double walled gift box from the blanks shown in FIGS. 1 and 2, there is shown in FIG. 3, a first stage of construction of the gift box. Glue is applied to outer end panels 18 a, 18 b such that tabs 60 are secured to them. Alternatively glue may be applied to the tab 60 before placement of the stiffening sheet 10 on the blank 20. Stiffening sheet 10, has been placed such that base panel 40 is in registry with main panel 12 of the tray forming blank 20 which may form a cover or base box. Glue G is applied to the inner side walls 16 a, 16 b which are then folded about fold lines 34 a, 34 b into flat face contacting relationship with an upper surface of opposed side panels 42 a, 42 b as shown in FIG. 4. It can be seen that tabs 26 are placed in overlapping relationship with gusset panel 30.

Outer side walls 14 a, 14 b are then folded inwardly about fold lines 48 a, 48 b inwardly to lie in overlapping relationship with the base panel 40 of the stiffening sheet 10.

In consequence of folding outer side walls 16 a, 16 b into overlapping relationship with base panel 40 gusset panels 28 are folded into an overlapping relationship with outer end walls 18 a, 18 b and gusset panels 30 are folding into an overlapping relationship with trapezoidal opposed end panel 44 a, 44 b.

Optionally, gusset panels 28 are secured to outer end walls 18 a, 18 b by Glue G applied to gusset panels 28 as shown in FIGS. 3, 4 and 5. It is envisaged in the illustrative embodiment that the package will be shipped in a configuration illustrated by FIG. 5, although the configuration in FIGS. 6 and 7 is also an option. Gluing gusset panels 28 to outer end walls 18 a, 18 b provides the additional benefit that the outer end walls 18 a, 18 b are erected automatically when the side walls are manipulated into an erected position. Optionally, inner end walls 20 a, 20 b are then folded about fold lines 38 a, 38 b into overlapping relationship with gusset panels 28, 30 and trapezoidal opposes end panels 44 a, 44 b to form a partially assembled tray of a double walled gift box that can be shipped or distributed in a flat form, thus saving on distribution costs.

FIGS. 7, 8 and 9 illustrate one possible method of assembly of the package. The flat collapsed form of the tray 2 can be assembled for use by raising the inner end walls 20 a, 20 b and the outer end wall panels 18 a, 18 b to be substantially perpendicular to the base panel 40. As a consequence of doing so, inner side walls 16 a, 16 b and outer side walls 14 a, 14 b are raised into a substantially perpendicular alignment to the base panel 40. This is achieved by gusset panels 28, 30 forming a connection between outer side panels 14 a, 14 b and the outer end wall panels 18 a, 18 b. The end walls, inner and outer, 20 a, 20 b, 18 c, 18 b respectively, can be raised by applying a force in the direction of arrows D4.

In an alternative method of assembly the package may be assembled starting from the partially assembled tray illustrated in FIG. 5. The opposed outer end walls 18 c, 18 b may be raised to be perpendicular to the base panel 40, this automatically raising the outer side walls 14 a, 14 b to be perpendicular to the base panel 40. Inner end walls 20 a, 20 b may then be folded within the tray such and locked in position either by tabs 24, 22 or by adhesive.

When gusset panels 28 are not secured to the outer end walls 18 a, 18 b the assembly process may include the further steps of folding the outer end walls and the outer side walls separately and of folding and tucking the gusset panels 28 into position.

Turning to FIGS. 10, 11 and 12 it can be seen that when the flat collapsed tray 2 is assembled the weakened line 61 breaks separating tab 60 from the remainder of the trapezoidal opposed end panel 44 a. The separation of tab 60 from its respective trapezoidal opposed end panel 44 a, 44 b is achieved as a consequence of relative movement between each trapezoidal opposed end panel 44 a, 44 b and each outer end wall 18 a, 18 b. In the preferred embodiment this relative movement can be viewed as upward movement of each trapezoidal opposed end panel 44 a, 44 b away from the main panel 12 of the tray forming blank 20, or downward movement of each outer end wall 18 a, 18 b towards the main panel 40 of the stiffening sheet 10.

Once the outer end walls 18 a, 18 b and outer side walls 14 a, 14 b are substantially perpendicular to the base panel 40, the inner end walls 20 a, 20 b are folded inwardly of the tray 1, see FIGS. 12 and 13, such that the tab 24 engages with the aperture 46 of the stiffening sheet 10.

The engaging edges 22 of the inner end walls 20 a, 20 b engage the edges 25 of the inner side walls 16 a, 16 b to complete assembly of the tray 1, as shown in FIG. 13.

Optionally, the tabs 24 and 22 may be removed and inner end walls 20 a, 20 b may be secured by glue or other bonding agent.

It is envisaged that the tray 1 may be assembled either by hand or automatically such as by a machine.

By providing tab 60 with a weakened line 61 the stiffening sheet 10 can be secured to the tray forming blank 20 by securing the tab 60 to the tray whilst being the tray is assembled and shipped in a flat collapsed form. A flat collapsible blank has the advantage of being readily shipped and distributed; the provision of tabs 60 a allows a tray to be assembled from the flat collapsed form in a controlled and predictable manner without tearing or deformation.

When the flat collapsed tray 2 is assembled into a set up condition the weakened line of severance 61 coupling each tab 60 to a respective opposed end panel 44 a, 44 b breaks thereby separating the opposed end panels 44 a, 44 b of the stiffening sheet 10 from the outer end walls 18 a, 18 b of the tray forming blank 20. The breaking action is achieved as a consequence of the finite thickness of the sheet material which forms the tray forming blank 20 and that forming the stiffening sheet 10. This breaking action can be enhanced by offsetting the fold line 50 a,50 b between the opposed end panel 44 a, 44 b and the main panel 40 of the stiffening sheet 10 from the fold line 36 a,36 b hinging the outer end wall 18 a, 18 b and the main panel 12 of the tray forming blank 20.

This offsetting may be achieved by configuring the main panel 40 of the stiffening sheet 10 such that it is shorter in dimension between its opposed end panels 44 a, 44 b than the dimension of the main panel 12 of the tray forming blank 20 between its opposed outer end walls 18 a, 18 b.

It also allows provision of a double walled tray having a stiffening sheet wherein in an assembled form the stiffening sheet is effectively suspended by the securing means between the inner side walls and the opposed side panel. In the illustrative embodiment, this is achieved using adhesive. The suspension of the stiffening sheet as described may provide an additional cushioning benefit which protects articles placed within the gift box.

FIGS. 14 and 15 illustrate alternative embodiments of the present invention in FIG. 14 a tab 160 is hinged to a free edge of each trapezoidal opposed end panel 44 a, 44 b by a weakened line of severance 161. In FIG. 15 tab 260 is struck from the material which forms the trapezoidal opposed end panel 44 a, 44 b tab 260 is disposed at a free edge of the trapezoidal opposed end panel 44 a, 44 b and defined in part by a weakened line of severance 261 and in part by a cut line which separates the tab from it respective trapezoidal opposed end panel 44 a, 44 b and in part by the free edge of the trapezoidal opposed end panel 44 a, 44 b.

The embodiments shown in FIGS. 14 and 15 are similar in many respects to the embodiments described above and shown in FIGS. 1 to 13, therefore like reference numerals have been used, with the prefixes “1” and “2”, to indicate like features of the embodiments shown in FIGS. 14 and 5.

The embodiments shown in FIGS. 14 and 15 the also rely on relative movement between a tray forming blank, such as that of FIG. 1, and the sheets 110, 210 to separate the tabs 161, 261 from the sheets 110, 210.

The relative movement in the embodiments of FIGS. 14 and 15 can be viewed as downward movement of each trapezoidal opposed end panel 44 a, 44 b away from the main panel 12 of the tray forming blank 20, or upward movement of each outer end wall 18 a, 18 b towards the main panel 40 of the stiffening sheet 10.

The relative movement required to separate the tabs 160, 260 is opposite to that of the illustrative embodiment. This may be achieved by providing the sheet 110, 210 as an external sheet rather than as an internal sheet according to the illustrative embodiment. The tab 160, 260 could therefore be provided in the tray for forming the blank rather than in the stiffening sheet. Of course this may be undesirable in packaging intended to be used a gift box since the broken tab 160, 260 may be visible unless further packaging is used. It is also envisaged that the present invention could be used in other forms of packaging and is not limited to gift boxes.

FIG. 16 illustrates a plan view of a stiffening sheet 310 according to a fourth embodiment of the present invention. In this embodiment it can be seen that the opposed end panels 344 a, 244 b are rectangular in shape, as distinct from the trapezoidal shape of the previous embodiments. A securing tab 360 is struck from the each of the opposed side panels 342 a, 342 b. The securing tabs 360 are coupled to the opposed side panels 342 a, 342 b along frangible connections 361. Frangible connections 361 are disposed along an edge of apertures 346 c. Apertures 346 c are struck from opposed side panels 342 a, 342 b.

Turning now to FIG. 17 it can be seen that the stiffener sheet 310 has been overlaid on a blank for forming a tray 320. Blank 320 is substantially the same as blank 20 shown in FIG. 1. Glue is then applied to the inner liner or stiffening sheet 310 along panels 342 a, 342 b. Panels 316 a, 316 b are folded and secured to panels 342 a, 342 b respectively. Panels 316 a, 316 b and panels 342 a, 342 b are then folded to overlay main panel 340, to produce a similar arrangement to that shown in FIG. 5.

Alternatively it is envisaged that glue may be applied to stiffener sheet 310 such that the inner side walls 316 a, 316 b are secured to the inner sheet only by securing tab 360. It is envisaged that other securing means may be employed in alternative configurations provided that the side and end walls of inner liner 310 are capable of movement relative to the side or end walls of tray blank 320. Optionally, panels 328 may be secured to opposed end walls 344 a, 344 b of the inner liner 310, by application of glue or other bonding agent. The constructed package may then be assembled into a tray as described previously.

In this way, means is provided for securing the inner liner 310 to the tray forming blank 320 whilst the package is constructed.

It will be appreciated that a gift box may be created by assembling of a first tray for forming a base and a second tray for forming a cover, wherein the base and cover are dimensioned such that one may fit within the other in a setup condition. In alternative embodiments the gift box may only comprise a top cover or base having a tray according to the present invention, the other of said top cover or base being provided by other means known in the art.

The entire box may be formed with conventional cutting, adhesive laying, and folding equipment. The stiffening sheet is cut and scored in a single operation and is placed in a single step. The initial perpendicular folding of the ends and sides insures precise alignment of the stiffener. No special provision is required for the precise aligning of detached parts when they are juxtaposed or are glued in place. No separate requirements for special aligning, placing, and bonding steps are present.

The bending of the sides along scores in the stiffening sheet automatically aligns and precisely positions the central panel of the stiffening sheet with respect to the main panel of the tray sheet as the side and end panels of the tray sheet are bent upward. The stiffening sheet is automatically locked in position by the inward folding and gluing of the outer side panel halves which would otherwise contact the inner surfaces of the inner side panel halves of a double walled box tray.

Savings result from no increases in the steps to handle the outer sheet when forming a double walled tray and no requirements to spread adhesive over the large main panel of the tray-forming sheet. Further increased savings result from not requiring precision placement equipment for aligning two large panels after gluing. The invention has the added advantage of reducing rejects from misaligned glued panels. Speed of production may be increased by the elimination of need for precise alignment before adhering large panels. Additional savings result from reduction of adhesive requirements, elimination of added adhesive requirements, and elimination of precision aligning and positioning equipment. The look and feel of the finished box may be enhanced by not requiring adhesive under the main panels.

While the invention has been described with reference to specific embodiments, modifications and variations of the invention may be constructed without departing from the scope of the invention, which is defined in the following claims.

It will be appreciated that whilst the invention described herein is directed to a double walled tray for a gift box, the present invention may be employed in any packaging system comprising two blanks in which a first blank is to be secured to a second blank pending further processing of the two blanks.

It is envisaged that in yet further embodiments of the invention that the securing tab may be replaced with an alternative fixing device capable of providing means for securing the inner liner to the outer tray while the package is constructed and/or processed, without departing from the scope of the present invention.
